ASX Release 17 October 2011 50 metre thick Coal at Bacchus Marsh. Mantle Mining Corporation Limited (ASX: MNM) “Mantle”, is pleased to provide the following update on activities at the Company’s 100% owned Bacchus Marsh Brown Coal Project: The Bacchus Marsh project, located 50km west of Melbourne and a similar distance north of the Port of Geelong (Figure 1), contains an Exploration Target of 1-2 Billion tonnes brown coal (details on last page). Figure 1: Bacchus Marsh Project Location. Figure 2: Typical coal (from hole MBM3). Highlights: ? The first 4 holes of a 15 hole drill program have been completed. ? In excess of 50m coal thickness was intersected in 2 of the holes. ? Total cumulative coal thickness intersected in the 4 holes was >25% increase on that predicted (146m Vs 116m). ? The program is designed to report an Inferred Resource in accordance with the principles and guidelines of the JORC Code.

Mantle has executed preliminary agreements with Exergen Pty Ltd to develop the Bacchus Marsh Coal Project. Exergen has developed a clean coal technology that, when teamed with modern coalfired power station technology, is expected to deliver up to 40% CO2 emissions reductions. The technology is known as Continuous Hydrothermal Dewatering (CHTD) and is patented worldwide including in Australia, Indonesia and China.

Exergen’s major cornerstone investors include; TATA Power, India’s largest private power utility, as major coal off-taker, Leighton subsidiary Thiess, the world’s largest supplier of outsourced mining services, Itochu, Japan’s 3rd largest trading house with extensive coal trading experience, and Sedgman, a global specialist provider of mineral engineering solutions. The agreements executed to date (MOU and Pre-JVA) contemplate the following: ? Executing Substantive Agreements for a 50/50% JV for exploration and mine development, ? Construction of a 50tph demonstration facility and then an export project by Exergen, ? Mantle being licenced to utilise CHTD on its 50% of the coal deposit. Figure 9: CHTD Pilot Plant Processing of Bacchus Marsh coal (56.7% moist) and resulting briquettes (9.5% moist). A two tonne bulk sample of Bacchus Marsh coal was processed at the CHTD pilot plant. Laboratory analysis of the bulk trial product confirmed that transformation of the coal had successfully occurred on a continuous basis. Secondary dewatering and pressing of a representative sample of low moisture briquettes was also achieved at the pilot plant. Run of Mine coal moisture content of 56.7% was reduced to a briquette moisture content of 9.5% (Figure 9).
